Tropical Storm Erin is rapidly intensifying in the Atlantic and is expected to become the first major hurricane of the season, with projections indicating a shift in its path. Various models have aligned on its trajectory, forecasting that Erin will strengthen significantly as it moves westward. As distribution of sandbags begins in the US Virgin Islands, residents are closely monitoring the storm, with the latest updates suggesting it may reach Category 3 intensity. Despite the potential for significant strengthening, forecasters indicate that Erin is unlikely to impact the US mainland directly.
